Force sensor and display device including the same

A display device, comprising:

• a display panel;
• a metal plate and a filling member disposed on same layer on a bottom surface of the display panel, wherein a material of the metal plate differs from a material of the fill in g member;
• a fingerprint sensor disposed on a bottom surface of the filling member and that overlaps the filling member;
• and
• a bonding member disposed between the fingerprint sensor and the filling member and that bonds the fingerprint sensor to the filling member,
• wherein a side surface of the filling member and a side surface of the metal plate are adjacent to each other.

A display device, comprising:

• a display panel;
• a metal plate disposed on a bottom surface of the display panel, wherein the metal plate includes a through hole;
• and
• a filling member disposed in the through hole on a same layer as the metal plate on the bottom surface of the display panel, and that includes a different material from the metal plate,
• wherein at least a part of a side surface of the filling member and a side surface of the metal plate are spaced apart from each other with an air gap therebetween, and
• wherein a thermal expansion coefficient of the filling member is greater than a thermal expansion coefficient of the metal plate.
